You need $20k for a new engine and a new turbo kit (or at least new turbos) for a reliable car at 500 whp.

 

From what I have been reading online it sounds like just rods and pistons. I would probably do studs anyway just because they can never hurt and would probably also end up doing the springs and valves. Is any of that overkill for 500whp? Am I missing something? Are the injectors capable of that? Do I need a new fuel pump?

 

I'm wondering who your friends is, does he post on here, whats hes handle. what type of setup? what type of SC, ect....

Thanks, TimRod

 

No he isn't on here I will have to ask him what his set up is, but all his internals are stock. He pretty much only drifts with it though and it is stripped out.

 

You don't need head work for 500 whp. With the 700bb turbos you will make it without cams. Springs/valves only needed if you change cams and/or raise the rev limit. Since the 530bb only pumps hot air past 6k rpms, it does not matter. That said if you're dropping the engine, the cost is in the labor, so I would throw cams in.

If you don't have the money or DIY skills, this is all dreaming...

 

It all depends on what your budget is really. If your budget allows it buying a long block from IPP sounds like a good start.

 

I have both the money and the DIY skills. I work in a supercharger shop so I can do all the work right there. I want to keep the 530 so I will get some cams. So any input on the fuel system? Will it support it? I got this car planning to do a lot of work to it but ended up getting a couple other toys that I put my time and money into so I am not really that sure what the stock parts are capable of. I read a lot of differing info online too.

 

I would like to just build it from my current engine with the 530bb that I have. I would like to keep it under 5k for all the parts. All the labor will be done at the shop I work at and tuning will likely be done at Joetech since I am no longer close to vinny ten.

 

You can look at the efficiency charts for the turbocharger, not sure you will hit 500 but you will get close esp with cams. You can deliver enough fuel with a walbro 255 and a return fuel system. Voltage controlled stock pump and rising fuel pressure might not make it. The jump from 400 to 500 incurs lots of extra little costs. You could always try it and see where the tune taps out if you're doing it all yourself.

 

Yeah I know 500 is pretty close to the limit for the 530bb but I know some are making near 550whp too. If I fall a little shy like 480~whp I will be happy too. Thanks for the input on the fuel system I will probably do that. I may even look into an e85 option. I am using a e30 mix on my 135 and I love the 400whp and 450wtq on stock car with only ic, dp and, intake. So was it my understanding your input was rods and pistons are the only thing "required" and I should get cams just to push closer to that 500 mark?

 

Actually I maxed the 530 kit out at 450whp. That is all she had, cosworth, haltech, 600cc, 485 maxed out the JWT 530.

 

Hmm good to know. Maybe the ones I am finding over 500whp are just the few exceptions that get lots of attention because of it. I appreciate your input.

 

Don't shoot for numbers! Just get more out of the kit you have! No need to swap a motor when the one you have is running for a little more power. Also look lighten up you Z. JWT kits are old school and great and have worked for years when kept @ moderate power levels. GL and nice Z

 

Well the whole point is to make it noticeably faster than my 135 which is at 450whp and 450wtq. If I can't achieve that I may just sell it and try to finish my 260z build sooner since that will be in the 800whp arena.

 

From a BMW 335 owner I will say that will be tough! Again don't chase numbers and try to enjoy it as is if not sell it while it is in good working order.

 

Thanks for the tip. Its not that I don't enjoy it of course. I think the biggest problem was I got it planning to take it to the track often but since the tracks are so far away I almost never go. Having three sports coupes is overkill. Since my 135 is just about at its turbo limits I started seeing where the 530bb limits were and was finding 500+whp and 600+wtq which I think is worth the money to get the car there and sell the 135 but since not I may be posting it on here in a few weeks after some deeper research.

 

Yeah, you're missing something... You will need a fully built auto trans if you want the trans to hold that kind power with any longevity. That will cost $4500-$6500 depending on vendor and/or core charge.

 

Srs? Really? Wtf is this a joke......?

 

What is the tranny limit? I read it was 450tq which at 500hp I would only expect to be in the low 400tq.

 

Why would this be a joke?
